Pros & Cons of this particular Garrett turbo on a built B18C?

I'm building my B18 from the ground up (again), and I need some words of encouragement on picking a turbo. Top end was built for all-motor with Skunk2 Stage 2 cams, Endyn valves & springs, and I'll be keeping that head. Bottom end will have Eagle rods, and probably 9:1 pistons, but no idea which ones yet.

Aiming for 300+ whp, with room to grow.

The t3/t4 .63 57trim fits very well with my budget, and I'm hoping it'll fit well in my engine bay on the SLS manifold I bought.

 

that turbo can make 500hp, but that will be about all. you dont need to go gt, everyone forgets about the old workhorse t3t4.

the endyn valves, can they handle the heat of an abnormally aspirated engine?

 

mang i luv that turbo i running in with a .48ar and it freakin awsome on the street
b18c1 all stock internals w/170000 miles
neukin ramhorn 3dp and 3 thermal
317hp/225tq going strong for over a year now and yes i boost it and beat it daily

Good question. I'll fire off an email to Larry and ask him.

Would be just my luck though, that I'll need to swap valves. Nothing is ever easy with me.

 

the reason i ask is because i was going to purchase a head off of a fellow h-t member that dave from headgames had built, i asked him bout the head and he said it was bad *** for an n/a setup but for th epower and boost i wanted to run the valves couldnt handle the heat.

either way good luck with the build.

 

I know that this is hard to answer, but how much boost on that turbo will yield 300+? Are we talking 15-20 psi?

 

I've heard that 10-12psi will get you in the 300s with that turbo. Not bad.

 

I was wondering about the psi number because I (stupidly) bought a wastegate before I had a turbo picked out... I bought a 1bar Tial, and I was just trying to figure out if I should buy a different spring or not.

300whp is not a problem. Stick with the .63A/R. A 1bar spring is fine if the motor has been well-assembled to handle the power itself. But you will be at over 13.8psi ALL the time. 300whp is about 10-12 psi, the turbo runs out of a bit of usable energy at about 18-22psi. Use a different spring and a boost controller is planning to go to higher boost levels.

You don't want to look at PSI as a primary means to measure power. different Psi means different CFM of air at different times with different sized turbochargers. Not the best way to measure. Look at the power, and purpose of the your car, and use the turbocharger to help with your characteristics for what you're trying to achieve.

 

^^ Good info.

The car is not my daily driver. I only drove my all-motor car a few times a week.

It's mainly for cruising with the car club, and the occasional "highway mischief". Very rarely will it be taken to the track. I guess I'm just looking for a good street setup.

On most setups, it takes between 10-11psi to hit 300whp with a standard 57trim, but again that depends a lot on the setup, the fuel used, and the dyno it was on. My GSR made 315whp on ~10-10.5psi on a Dyno Dynamics dyno.

AMEN to that!!! Everyone thinks that if you want to make more than 350whp, they must go to a ball bearing turbo. In reality, most people would be just fine with a 57trim. The practical range for the turbo limits it at around 460whp, but that's still plenty of power for most stock sleeve, piston/rod combos. Another option is the journal bearing GT32 series like the GT3255b that i have on my GSR. It spools faster than the 57 trim but makes about the same power; however, the top end power potential is somewhat limited. It is a 47 lb/min turbo compared to the 48 lb/min with the 57trim and 50 lb/min on the 60trim.

 

Just ordered my turbo. TunerToys FTW with awesome pricing.

 

the T3/TO4E .63 a/r 57 trim is a great turbo. click my sig to see the results I got with that turbo. The powerband will be different but you'll get the job done, no question.

 

Think my RC 370 cc injectors are going to be too small?

 

yea i guess i forgot to tell ya im at 10 psi and 317hp on b18c1

370cc injectors wont get you to 300whp let alone have room to grow. I would start out with a set of 880cc injectors so you have that room you're looking for...

 

b20/vtec 420whp@ 17psi @8500rpm and still going up.

57-trim FTW!!!

 

11.889@116 with 10lb on a stock GSR with the same turbo

 

i'm running the same as you asked about only in a 60 trim. i like it but am thinking of geting the 57 or even the 54 trim in a smaller a/r in hopes of quicker spool. not that the 60 is a dog or anything...i just dont q-mile that much anymore. i think the 54 or 57 might be more fun on the street. other than that it's been a great turbo over the last 4k miles. usualy get full boost while rolling in upper gears at about 5k with a shity ex and stock intake mani.

 

i tuned my neighbors stock gsr eariler this summer to 300hp and 210 ftlbs with the .63 ar 57 trim turbo. it was with a peakboost ver1 kit, and done on 8 creeping to 9ish psi at 8200. with a more aggressive tune on the same boost level i could have made between 310 and 320whp. his car hits its full boost of 8-9 psi around 3500-4000 rpms depending on which gear we are in.


you probably want to get like 550 or 780cc injectors which can take you up to the 400 hp range with the 780s. what are you going to do for fuel and ignition management?

Am running a Walboro 255 fuel pump, and am selling my Hondata to run Neptune.

 

I'm running the same turbo on my GSR and it made 275 @ 9psi and 398 @ 16psi. I need to go back and get a retune without a cat and a couple other things that are robbing power. You will like it...a lot of fun!

 

my friend has the same turbo on his semi built B16.. rods/pistons/ARP studs and he made 453whp/280tq@21psi...

i just finished my turbo kit install on my GSR and with that turbo i made 284whp/192tq@7psi AFI B-series street kit!!!

 

The 57 trim is one of those turbos that people overlook, but it's a great turbo for a lot of setups and is capable of a good amount of power....especially for the price

 

yeah it is people do overlook it!!! i mean it spools pretty nicely i think!!! full boost by 4500rpm in my car and there was no sign of it dieing off on the dyno!!!
